Easy solution...(for a beginners mistake...)

Well, the pointer

        aBrickSet

in eg.

        //read voxel
         
        valueGet = (GLubyte*)aBrickSet->getVoxelAddr(2,2,2);

actually was a NULL pointer. I was not aware of the fact, that the
operator

        ()
 
of

        voBrickSetCollectionIterator

returns NULL when the whole collection was traversed.

The following does the job for my case:

valueGet = (GLubyte*)
aVolume->getCurrentBrickSet()->getVoxelAddr(2,2,2);

or
        
valueGet = (GLubyte*)aVolume->getVoxelAddr(2,2,2);
